Study On The Hospital Infection And Its Influencing Factors In A Military Center Hospital In Hunan District

Objective:Select hospitalized patients during January1,2012to December31,2012in a military central hospital in Hunan district as our investigation object. To understand the hospital infection epidemiological characteristics and risk factors of this hospital during2012by using cross-sectional study, and provide reliable scientific basis for prevention and control of hospital infection the for the future, and provide scientific and reliable health decision-making basis for other medical institutions to prevent and control hospital infection.Methods:Describe and analyze the social demographic characteristics, the incidence and the epidemiological characteristics of hospital infection of the hospitalized patients of a military center in Hunan district hospital during the period of January1,2012to December31,2012, by using cross-sectional study, analyze the related risk factors for hospital infection by using a non-matched case-control study. Use chi-square test, multi-factor unconditioned logistic regression analysis for statistical analysis.Results:(1) We investigated23574complete cases in this hospital, at a rate of99.84%. In those cases,60.74%were men, while women accounted for39.26%; Less than18years of age patients accounted for16.22%, aged18to24patients accounted24.05%,45to59years patients accounted for24.00%, over the age of60patients accounted for35.73%; Marriage was given priority to with the married, accounted for95.33%; Cultural degree was given priority to in a technical secondary school, accounting for30.13%;61.33%of hospitalized patients were with basic diseases; Surgical(45.66%) and medical(40.15%) patients accounts for most of hospitalized patients; Hospitalization days of7to15days is the majority of hospitalized patients, accounted for36.23%.(2) In this survey, the rate of hospital infection was3.96%, the cases of infection rate was4.26%. The top five pathogenic bacteria were pseudomonas aeruginosa, klebsiella pneumonia, e. coli, staphylococcus epidermis and staphylococcus aureus. The top five infections were the lower respiratory tract, upper respiratory tract infection, urinary tract, gastrointestinal tract and surgical incision infection.(3) The hospital infection rate of different gender, marital status, educational level of hospitalized patients were no statistically significant (P>0.05), the hospital infection rate of different ages of hospitalized patients was statistically significant (P<0.05), and the hospital infection rate of under the age of18and over60hospitalized patients was the highest, the second was45to59years hospitalized patients, and the hospital infection rate of18to44years hospitalized patients was the lowest.(4) The hospital infection rate of different departments was statistically significant (P<0.05), the hospital infection rate of surgery in the hospital was the highest (4.43%), followed by internal medicine (3.72%) and department of gynaecology (3.36%), then the hospital infection rate of the pediatric(3.19%), the hospital infection rate of the recovery was lowest(2.88%).(5) The hospital infection rate of different number of hospital admission, different number of hospital diagnosis were no statistically significant difference (P>0.05); The hospital infection rate of different hospitalization days of hospitalized patients was statistically significant (P<0.05), the hospital infection rate of the length of hospital stay above30days of hospitalized patients was the highest, at the rate of6.09%. The second hospital infection rate was the length of hospital stay of7to15days of hospitalized patients, at the rate of3.58%; The hospital infection rate of length of hospital stay below7days and16to30days of hospitalized patients was the lowest, at the rate of3.41%;(6) The hospital infection rate of hospital patients whether treating with invasive operations (using breathing machine, endotracheal intubation, urinary tract intubation, intravenous cannula, drainage tube, hemodialysis) or not was statistically significant (P<0.05), the hospital infection rate of hospital patients whether treating with hormone therapy, radiotherapy, chemotherapy and antimicrobial treatment or not was statistically significant (P<0.05), the hospital infection rates of using invasive operations, hormone therapy, radiotherapy, chemotherapy and antimicrobial treatment of hospitalized patients were higher than those who did not.(7) The hospital infection rate of hospitalized patients who had diabetes, dyslipidemia, and malignant tumor were higher than these hospitalized patients without diabetes, dyslipidemia and malignant tumor disease(P<0.05); The hospital infection rate of hospitalized patients whether with hypertension, cardiovascular disease, digestive system disease had no statistical significance (P>0.05).(8) The hospital infection rate of hospitalized patients with abnormal levels of ESR and C-reactive protein, albumin were higher than those hospitalized patients with normal levels (P<0.05); The hospital infection rate of hospitalized patients whether their transaminase/WBC/HGB level normal or not had no statistical significance (P>0.05).(9) Age<18years old, age≥60years old, with malignant tumor, department of surgery, internal medicine, pediatrics and gynecology, use of endotracheal intubation, drainage tube, arteriovenous catheterization, chemotherapy treatment, and antimicrobial agents were the risk factors of hospital infection.Conclusions:1. The rate of hospital infection was3.96%, the cases of infection rate was4.26%. The top five pathogenic bacteria were pseudomonas aeruginosa, klebsiella pneumonia, e. coli, staphylococcus epidermis and staphylococcus aureus. The top five infections were the lower respiratory tract, upper respiratory tract infection, urinary tract, gastrointestinal tract and surgical incision infection.2. Age<18years old, age≥60years old, with malignant tumor, department of surgery, internal medicine, pediatrics and gynecology, use of endotracheal intubation, drainage tube, arteriovenous catheterization, chemotherapy treatment, and antimicrobial agents were the risk factors of hospital infection.
